The European Chemicals Agency, ECHA, has published a list of over 21,000 REACH-registered substances mapped in its 'chemical universe'. The substances have been divided into five pools based on the regulatory actions in place, initiated or considered for them. It also highlights that there are still thousands of substances for which possible actions have not yet been determined. The chemical universe does not indicate whether a substance’s use is safe or not – it is mainly to help authorities focus their actions. The assignment to a pool is also not permanent – substances will move from one pool to another over time when new information becomes available or priorities change.

The European Chemicals Agency (ECHA) has mapped substances on the EU market in a bid to help authorities identify, plan, monitor and regulate substances of concern. There are three groups of substances:
• 270 substances are high priority for risk management.
• 1,300 substances are high priority for data generation.
• 450 substances are low priority as sufficient regulation exists, and 500 substances have been concluded to be currently of low priority after assessment.
ECHA mentioned the focus is on the 4,700 substances registered above 100 tonnes. And more than 40% of these substances have been allocated to the above categories. The substance list will be published at the end of the year.
